i have 2 physical machines
physical machine 1 ( base os + (storage server vm) + (rhevm+dns) + windows 2008 AD server )
physical machine 2 (rhevh)
kindly update what is the correct order to bring the machines down and then up, because whenever i bring the machines up the master domain(iscsi) is not found 
my current order is , 
1) place storage domain in maintenance
2) place rhevh in maintainence 
3) power off the storage vm 
4) power off rhevh
